NILLIAM P. HUSSEY, OF INDIANAPOLIS, INDIANA, ASSIGN OR TO THE STAND ARD DRY KILN COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORA- TION OF INDIANA.

. 1 STEAM-HEATING APPA RATUS- 1'0 all whom it may concern.-

of lndianapois, county of Manon, and State of Indiana, have invented a certain new and useful bte'am-tleating Apparatus; and I do hereby declare that the iollowing is a full,

clear, and exact description thereof, refer ence being had to the accompanying draw ings, in which like letters reter to like parts.

'lhe ob ect of this invention is to improve the heating apparatus in dry-kilns and other kinds of drlers where the material .s moved through the drier by way of simplifying the construction and arrangement and increasing the degree of heat as the material to be treated passes through the drier.

One feature of the invention consists in a plurality of series of parallel longitudinallyextending heating-pipes, the dil'lerent series varying in length and superimposed upon each other, there being one header at each end of the entire apparatus, which has communicating connection with all series of heating-pipes.

The full nature of this invention will be more fully understood from the accompanying drawings and the following description and claims.

In the drawings, Figure 1 is a transverse section of the heating apparatus and the lower part of a truck. Fig. 2 is a side elevation of the inlet end of the pipes. Fig. 3 is a side elevation of the outlet end thereof.

' Fig. 4 is a central longitudinal section of parts, showing the expansiomjoints. Fig. 5 is a plan view of the apparatus centrally broken away in places. Fig. 6 is a plan View of the lower series of pipes and end connections, the inlet-header being shown in horizontal section. Pig. 7 is a plan view of the second series of pipes and connections. Fig. 8 is a similar view of'the lower series of the pipes and connections. Fig. 9 is a transverse section through the pipe leading to the second series of heating-pipes, an elevation of the spreader for supporting said pipes, a

section across the three pipes in the lower ser.es of heating-pipes on which the spreader rests, and a support for said lower pipes broken away at its lower ends. Fig. 10 is a transverse section through the pipes leading to the second and third series of heating- Speeification of Letters Patent.

l pipes and four pipes of the lower series of Be it known that I, WILLIAM P. HUSSEY, l

heating-pipes, showing in elevation a modihed two-piece spreader and the means for supporting the lower pipes broken away at its ends.

ln'the drawings, there is shown a railway or truck'track consisting of rails 10 and ties This track is adapted for a truck 12, upon which the material to be dr.ed or treated is conveyed through the drier.

Three series of heating-pipes are showna lower longer series of pipes 13, a shorter series of pipes 14, carried by spreaders 15 upon the pipes 13 and staggered with relation thereto, and a still shorter series of pipes 16 on the spreaders 15, mounted on the series 14 immediately be.ow and also staggered over the last-mentioned pipes. The lower series of pipes is mounted on the cross-ties or supports 11 and longitudinally of the track-rails, and the entire series of heating-pipes in the staggered arrangement mentioned making an assemblage of pipes that extend above the track-rails and slope or taper on each side upward and away from the track-rail, so the wheels of the truck whi'.e running on the track will not be in danger of engaging the heating-pipes and the heating-pipes will be up close to the 'material carried by the truck.

In operating the drying apparatus herein shown it is desirable that as the truck carrying the material to be treated moves on through the drying apparatus or structure the heat imparted by the pipes proportionally increases, so that the material on the truck receives the highest degree of heat in the latter part 01 the operation. Hence the lower series of pipes 12 extends for the entire length of the track, while the series of pipes connected with the main header 20 by a short pipe 26, and the headers for the other contraction, and the pipes are closer to the material o be treated and the heat is greater series of pipes are connected with said main as the truck proceeds.

header-20 by pipes 27 and 28, respectively.

. The pipes 26, 27, and 28 are centrally located one above another and are each in a horizontal plane with the series of pipes to which they supply steam. The pipes 27 and 28 have valves 29, so that either or both may be closed. A

The main outlet-header 30 is. connected by a pipe 31 with a subordinate outlet-header 32, which in turn is connected with the pipes of the lower series.

The connection between the two lateral pipes of each series and the corresponding headers is a rigid one; but the connections between the intermediate pipes of each series and one of the headers is effected b expansion-joints, consisting of pipes 33 an nuts 34 and 35, which include between them coinpres'sed packing 36. The nut 34v connects 0th pipes 33'and 13, while the nut 35 com presses thepacking around the smaller pipe or outlet-header 32. There are similar subordinate outlet-headers 37 and 38 in the other series of pipes, that are similarly connected with its respective series, and from each there is a pipe 39 and 40, respectively, that leads centrally to the main header 30, with which they are connected by expansion-joints similar to those described. All three series of heating-pipes terminate near the main outlet-header 30; but the upper series are quite distantly removed from the main inletheader 20. The main inlet and outlet headers 20 and 30 are vertically disposed, as the three pipes connected with them are arranged over them. A pipe 45 with a loose joint leads from the outlet-header 30 to a wastepipe 46. The pipe 27 is carried by a small spreader 47, that is triangular in general form,

'with a concave seat for its pipe in its apex I claim- 1. In a heating apparatus, a plurality of superimposed series of heatin -pipes, each series of pipes being shorter tiian the next lower series of pipes, a main header at each end of the apparatus, a subordinate header at each end of each series of pipes, and a communicating connection between the main header and each subordinate header at each end of the apparatus.

2. In a heating apparatus, a plurality of superimposed series of heating-pipes, each series of pipes being shorter than the next lower series of pipes, a main header at each end of the apparatus, a subordinate header at each end of each series of pipes, a communicating connection between the main header and each subordinate header at each end of the apparatus, and independent means in each of said communicating connections for controlling the admission of steamto each series of pipes.

3. In a heating apparatus, a plurality of superimposed series of heating-pipes parallel with each other, each upper series of pipes being shorter than the next lower series of pipes, a main header at each end of the apparatus, a subordinate header at each end of each series of pipes, a centrally-located pipe leading from each subordinate header to the corresponding main header, and valves in all but one of said centrally-located pipes at the steam-inlet end of the apparatus.

4. In a heating apparatus, a plurality of superimposed series of heating-pipes parallel with each other, each upper series being shorter than the next lower series of pipes, a main header at each end of the apparatus, a subordinate headerat each endof each series of pipes, a centrally-located pipe leading from each subordinate header to the corresponding main header, and expansion-joint connections. between the main and the subordinate ()utletheaders.

In witness whereof I have hereunto affixed my signature in the presence of the witnesses herein named.
